WHlFFLETREE-HOOK.

SPECIFICATION forming part of Letters Patent No. I4=4,.t20, datedJanuary 13, 1891.

Application filed August 11, 1890- Serial No. 361,718. (No modell) Toall whom it may concern-.-

Be it known that I, WILLIAM W. CHAND- LER, a citizen of the UnitedStates, residing at Long Prairie, in the county of Todd and State ofMinnesota, have invented certain new and useful Improvements in Wagon-Pole, VVhiffletree, and Neck-Yoke Hooks, of which the following is aspecification, reference being had therein to the accompanying drawings.

My invention relates to an improvement in wagon-pole, Whiffietree, andneck-yoke hooks; and it consists in the construction and arrangement ofparts hereinafter described and claimed.

The object of my invention is to provide a simple, inexpensive, andconvenient device for securing the cockeye or trace to a singletree or astrap to a pole or neck-yoke. I obtain this object by the constructionillustrated in the accompanying drawings, wherein like letters ofreference indicate corresponding parts in the several views, and inwhich- Figure l is a perspective view of a pole with the attachment.Fig. 2 is an elevation of a whifiletree. Fig. 3 are detail views inperspective of the catch and a portion of the retaining-arm.

In the drawings, A represents the pole, singletree, or yoke having alateral groove co in its end and a retaining-shoulder a to prevent thestrap from being forced back against the pivotal portion of theretaining-arm.

B is a pivotal retaining-arm made of a bent bar having its outer end I)bent at right angles and arranged to fit in the groove to in the end ofthe pole. The inner end of this arm is bent at right angles and has aflattened shank 1) extending therefrom formed with a curved or convexedupper face anda flat under face. Through this shank, near the arm, ispassed a pivot O, retaining the same in place and permitting it to bemoved horizontally. In the outer edge of this shank b is formed a groove0 with vertical sides.

D is a spring-dog pivoted on a suitable support cl on the tongue andhaving a tooth E, with beveled sides on its forward end which engage inthe notch 0. Between therear portion of the dog and the pole is a spiralspring F, normally holding the toothed end of the dog down.

In operation the device is to be used as follows: When the strap or ringis to be placed on the pole, the toothed dog D is forced up by pressureon the spring-pressed end. The retaining-arm is then turned and thestrap slipped over the end of the pole or tree, as the case may be. Thearm is then moved back, and owing to the beveled shaping of the toothand the inclined face of the shank on the arm the dog is forced up untilthe groove 0 is reached, into which the tooth is immediately forced bythe spring locking the arm in place.

I am aware that many minor changes in the construction and arrangementof the parts of my device can be made and substituted for thosehereinshown and described without in the least departing from the natureand principle of my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a hook for the purposes specified, the combination, with thesupporting end having a transverse groove therein and a shoulder, of ahorizontally-swinging arm having its ends bent down at an angle, a shankon the lower part of the inner end having a groove therein and aninclined upper face, a pivot passing through the shank, and aspringactuated dog having a tooth on its end formed with beveled sides,substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM W. CHANDLER.
